But police confirmed the man was treated at the scene by paramedics before passing away and they described it as a “sudden death”.

An eyewitness, Kalli Capewell, who was on the bus taking her son to nursery, was in full view of paramedics working to revive the man.

She told The Herald: "I was on a bus but due to the ambulance being in the bus lane and no cars allowing the bus out, we were stuck behind the ambulance for a few minutes in view of the paramedics working on the gentleman.

"I did see the paramedic that was doing chest compressions stop and go towards the ambulance I think it might have been the point they realised there was no more they could do. He looked very saddened by this.
